I am one of the lucky ones who have picked up the khorus's at the "used " market price. I have been totally touchred by the performance of these speakers. I had compared against B&W, Theil (7.2) , Audio Physics and have found nothing that compares to the lifelike presentation these reveal. The break in is critical and I believe most are not patient enough to burn them in properly. The speakers are the best I have ever had and I anxiously await coming home to crank these up and enjoy what I find to be the best music I have ever listened to. The Orchard bay Spikes designed for these are definitely recommended and combined with good gear literrally out class anything I have ever heard. The used market prices are like the stock market, and if you can take advantage of acquiring as such is nothing short of a good value! I could go on and on about their merits, but will simply close by saying that These are as good as it gets with the current technology deployed in high end speaker systems!!
